Abstract
Disclosed is a battery pack system to supply current necessary to operate an external device, including a battery module including battery cells which can be charged and discharged, a temperature sensor, an auxiliary power unit to supply a charge and discharge pulse current to the battery module, and a controller to connect the auxiliary power unit to the battery module so that the charge and discharge pulse current is supplied to the battery module when a measured temperature (T) of the battery module is less than a set temperature (T) based on information detected by the temperature sensor before the battery module is electrically connected to the external device and to interrupt the supply of the charge and discharge pulse current to the battery module when the temperature of the battery module becomes equal to or greater than the set temperature (T) and an operating method of the same.
